Chiral conjugated polymers have emerged as promising candidates for next-generation technologies, including photodetectors, cryptographic systems, and spintronic devices. (1−9) In addition, recent studies have shown that this interesting class of materials can also preferentially transmit electrons with one spin orientation over that of the other, (10−12) a phenomenon referred to as the chiral-induced spin selectivity (CISS) effect.

Improving the Efficiency of All-Polymer Solar Cells by Morphology Control via Combination Approach: Polar Solvent Additive and External Electric Field Controlling the morphology of bulk heterojunction (BHJ) film, the optoelectrical active layer, in all-polymer solar cells (all-PSCs) is both delicate and challenging in the pursuit of high-performance organic solar cells. In this study, we achieved improvement on efficient of all-PSCs by integrating two straightforward processes.

External electric field treatment for improving the morphology and electrical performance of P(NDI2OD-T2)† Charge transfer characteristics of conjugated polymers are dominantly influenced by the morphology; therefore, pre- or post-treatment processes are essential for reducing the disorder in terms of intra- and inter-molecular structures. Herein, we propose an effective strategy known as external electric field (EEF) treatment to improve the crystallinity and alignment of conjugated polymers.
